Things to consider:
• blood flows „downhill”, follows a pressure gradient
• pressure gradient is generated by the heart
• the heart can not store blood –
what comes in, must get out
• the circulation is a closed loop
• valves in the heart only play a passive role
• the heart must cope with different needs
